Traditional motor designs use a fixed air-fuel mixture that does ok at low and high speeds, but not in the mid-range.

Honda added an Oxygen Sensor, which monitors the air/fuel ratio and automatically adjusts it as needed.

At cruising speed, Honda engines run on up to 20% less fuel than other comparably sized outboards.

The result? More power when you need it, and greater fuel economy.

Boosted Low Speed Torque, or BLAST, uses Honda’s patented spark advance system to propel the boat to plane in just seconds.

When you move the throttle quickly, BLAST is activated:

• The throttle body opens up
• The air-fuel ratio goes to a richer setting
• The ignition timing advances aggressively

This allows the engine to make more torque, or power.

“Hole Shot” is vastly improved, as more horsepower gets the hull up on plane quicker.

Honda’s 4-Front Corrosion Protection System fights off corrosion from harsh marine environments. This patented double-sealed, multi-layer paint process uses 4 different layers to protect the engine.

• The base is a corrosion-resistant Honda aluminum alloy, followed by a double-sealed treatment.
• An epoxy primer undercoat is applied.
• An acrylic resin metallic coating is baked on.
• A clear overcoat of acrylic finishes the process.

Honda engines have several other features designed to help protect them from the harsh marine environment:

• Sacrificial anodes protect the engine from galvanic corrosion.
• All fasteners and hardware are either stainless steel or a specially treated Dacro material.
• All wiring connectors are sealed to prevent water intrusion.
• Fresh water flush ports on select models allow you to flush the engine with a garden hose.

There's always plenty of electric power with Honda's “on demand” alternator. It gives you more charging power when you need it.

Our belt-driven system helps batteries to stay charged and keeps equipment going all day long.

In fact, the BF225’s “On Demand” 90 amp belt-driven alternator puts out the highest amount of amps in the outboard market.

Honda's alternator provides more electric power than the competition. For example, the BF200/225, shown in blue, has significantly more amps available than competitive four-stroke motors

Alternators, by the numbers

Honda advertises the real amps that you would see in real use. Some outboard manufacturers only advertise their total alternator output, measured at cool temperatures. This can be somewhat misleading

• Honda measures alternator output at normal operating temperatures. Most other manufacturers measure using a cool alternator, which produces more amps
• Honda advertises total amps and “charging amps.” Charging amps are the total amps minus the ignition’s requirements. For example, say an engine produces 27 amps in total. The ignition uses 5 amps, leaving 22 charging amps available to power accessories

Compare for yourself, and you’ll see: apples to apples, Honda motors give you the power you need.

Honda’s BF 75, 90, 135, and 150 feature three separate cooling systems.

• The block is kept slightly hotter, for more power
• The cylinder head is slightly cooler, for increased durability.
• The exhaust manifold also runs cooler.
